Enterprise Reliability Architect

Purpose of the role

To apply software engineering techniques, automation, and best practices in incident response, to ensure the reliability, availability, and scalability of the systems, platforms, and technology through them. 

Accountabilities

• Availability, performance, and scalability of systems and services through proactive monitoring, maintenance, and capacity planning.
• Resolution, analysis and response to system outages and disruptions, and implement measures to prevent similar incidents from recurring.
• Development of tools and scripts to automate operational processes, reducing manual workload, increasing efficiency, and improving system resilience.
• Monitoring and optimisation of system performance and resource usage, identify and address bottlenecks, and implement best practices for performance tuning.
• Collaboration with development teams to integrate best practices for reliability, scalability, and performance into the software development lifecycle, and work closely with other teams to ensure smooth and efficient operations.
• Stay informed of industry technology trends and innovations, and actively contribute to the organization's technology communities to foster a culture of technical excellence and growth.

Assistant Vice President Expectations

• To advise and influence decision making, contribute to policy development and take responsibility for operational effectiveness. Collaborate closely with other functions/business divisions.
• Lead a team performing complex tasks, using well developed professional knowledge and skills to deliver on work that impacts the whole business function. Set objectives and coach employees in pursuit of those objectives, appraisal of performance relative to objectives and determination of reward outcomes.
• If the position has leadership responsibilities, People Leaders are expected to demonstrate a clear set of leadership behaviours to create an environment for colleagues to thrive and deliver to a consistently excellent standard. The four LEAD behaviours are: L – Listen and be authentic, E – Energise and inspire, A – Align across the enterprise, D – Develop others.
• OR for an individual contributor, they will lead collaborative assignments and guide team members through structured assignments, identify the need for the inclusion of other areas of specialisation to complete assignments. They will identify new directions for assignments and/or projects, identifying a combination of cross functional methodologies or practices to meet required outcomes.
• Consult on complex issues; providing advice to People Leaders to support the resolution of escalated issues.
• Identify ways to mitigate risk and developing new policies/procedures in support of the control and governance agenda.
• Take ownership for managing risk and strengthening controls in relation to the work done.
• Perform work that is closely related to that of other areas, which requires understanding of how areas coordinate and contribute to the achievement of the objectives of the organisation sub-function.
• Collaborate with other areas of work, for business aligned support areas to keep up to speed with business activity and the business strategy.
• Engage in complex analysis of data from multiple sources of information, internal and external sources such as procedures and practises (in other areas, teams, companies, etc.) to solve problems creatively and effectively.

Embark on a transformative journey as an Enterprise Reliability Architect at Barclays. At Barclays, our vision is clear — to redefine the future of banking through resilient, observable, and highly scalable technology platforms. We are seeking an Enterprise Reliability Architect to join a cross-cutting engineering function focused on advancing enterprise reliability and observability practices across mission-critical applications.

In this role, you will help shape how reliability engineering is implemented across the organization by driving telemetry standards, resilience patterns, non-functional architecture, and proactive performance engineering. You will partner with application, platform, and engineering teams to improve reliability maturity at scale, not as a traditional product support function, but as part of a Center of Excellence for observability and reliability engineering.

This is an opportunity to influence engineering outcomes across multiple domains by defining best practices, closing systemic reliability gaps, and enabling teams to design for resilience, operability, and performance from the outset.

To be successful in this role, you will need the following:

• Experience establishing or scaling reliability, observability, or resilience practices across multiple teams or platforms.
• Experience partnering across engineering teams to influence non-functional architecture, operational readiness, and production resilience through technical leadership and consultative engagement.
• Experience driving proactive reliability practices including monitoring strategy, telemetry standardization, service health measurement, and performance optimization across multiple teams or services.
• Strong experience with observability and APM tooling such as OpenTelemetry, Elastic, AppDynamics, or Prometheus.
• Experience implementing resilience patterns such as Retry, Time Limit, Circuit Breaker, Bulkhead, Throttling, and Saga.
• Ability to act as a technical advisor by guiding best practices, influencing design decisions, and helping teams improve reliability maturity at scale.

Other highly valued skills include:

• Experience in financial services or other highly regulated, mission-critical environments.
• Knowledge of networking and security fundamentals, including VPC design, IAM, encryption, and secrets management.
• Experience with infrastructure and platform environments such as Red Hat, Windows, and Kubernetes.
• Familiarity with CI/CD and automation tooling used to support reliable software delivery.

You may be assessed on the key critical skills relevant for success in role, such as risk and controls, change and transformation, business acumen, strategic thinking and digital and technology, as well as job-specific technical skills.
The successful candidate will be based in Prague.
